Thermal State of Permafrost (TSP): The US Contribution to the International Permafrost Observatory Network

Romanovsky ARC 05-20578该提案将把阿拉斯加的大约66个钻孔与其他国家的类似观测连接起来，这样做将正式启动国际永久冻土观测站网络(INPO)。这项工作将使用标准设备和协议在阿拉斯加的井点和在选定的相当数量的俄罗斯井点协调数据收集工作。阿拉斯加和俄罗斯的钻孔温度数据集将提供基准，以重建过去的地表温度，评估近地表永久冻土温度和永久冻土边界未来的变化率，并为验证气候情景模型和温度再分析方法提供空间数据。这项提议是美国对拟议的国际极年永久冻土热状态(IPY/TSP)项目的贡献，该项目提议测量大量全球分布的钻孔中的温度，以便提供永久冻土温度在时间和空间上的“快照”。

RomanovskyARC 05-20578This proposal will formally link approximately 66 Alaskan boreholes with similar sets of observations in other countries, and in so doing will formally initiate the International Network of Permafrost Observatories (INPO). This work will coordinate data collection using standard equipment and protocols at the Alaskan borehole sites and at a selected and comparable number of Russian borehole sites. The Alaskan and Russian borehole temperature data sets will provide the baseline to reconstruct past surface temperatures, to assess the future rates of change in near-surface permafrost temperatures and permafrost boundaries, and to provide spatial data for validation of climate scenario models and temperature reanalysis approaches. This proposal provides the US contribution to the proposed International Polar Year Thermal State of Permafrost (IPY/TSP) project that proposes to measure temperatures in a large number of globally distributed boreholes in order to provide a "snapshot" of permafrost temperatures in both time and space.
